Title:
TRANSMITTER OUTPUT CALIBRATION
Document Type and Number:
WIPO Patent Application WO/2020/114365
Kind Code:
A1
Abstract:
A circuit includes a processor formed on a substrate to generate a digital output and a transmitter formed on the substrate. The transmitter is coupled to receive the digital output and generate a high-frequency analog signal from the digital output. The transmitter includes a power amplifier to amplify the high-frequency analog signal. A self-test circuit formed on the substrate is coupled to the high-frequency analog signal to generate a digital value according to the high-frequency analog signal and send the digital value to the processor to calibrate the transmitter.
